What is a self-consumption solar power generation system?

What is a self-consumption solar power generation system?

The generated electricity is consumed by factory equipment and more! Introducing a system aimed at a decarbonized society.

A "self-consumption solar power generation system" refers to a system that generates electricity using solar panels and consumes that electricity on-site, such as in factories, warehouses, stores, or offices, without selling it back to the power company, thereby reducing the amount of electricity purchased from the power company. This document provides a detailed explanation of the types of self-consumption systems. It contains information that is easy to reference when considering the introduction of a solar power generation system, so please take a moment to read it. [Contents] ■ Types of solar power generation systems ■ Types of self-consumption systems ■ Why self-consumption? *For more details, please refer to the PDF document or feel free to contact us.

Reduction case

Reduction case

The annual electricity costs vary significantly for self-consumption types! Introduction of reduction case studies.

We would like to introduce examples of reductions achieved through the "excess power selling type" and "complete self-consumption type." In a certain logistics warehouse, by implementing the "excess power selling type" system, the annual electricity cost was reduced from 16.6 million yen to 3.8 million yen, achieving a 77% reduction. Additionally, in refrigerated and frozen warehouses that use a large amount of electricity throughout the year, the "complete self-consumption type" system was implemented, resulting in an annual electricity cost reduction of 3.98 million yen. 【Other Reduction Examples】 ■ Complete Self-Consumption Type - Frozen/Refrigerated Warehouse: Annual electricity cost reduced from 35.64 million yen to 29.07 million yen (18% reduction) - Manufacturing Factory (total of 2 buildings): Annual electricity cost reduced from 10 million yen to 6.8 million yen (32% reduction) ■ Excess Power Selling Type - Manufacturing Factory: Annual electricity cost reduced from 12.2 million yen to 4.9 million yen (59% reduction) *For more details, please refer to the PDF document or feel free to contact us.

Generate power in-house, consume in-house! Self-consumption solar power generation.

Generate power in-house, consume in-house! Self-consumption solar power generation.

Contributing to the SDGs: It's cheaper to generate electricity than to buy it! Clean and inexhaustible solar energy is gaining attention. *Model case calculations available.

The EU meteorological information agency reported that the global average temperature in July 2023 reached the highest level recorded since observations began in 1840. In China, a temperature of 52.2°C was recorded in Turpan, while in Spain, 45.4°C was recorded in Catalonia, and Tunisia saw temperatures of 49.0°C. Various countries experienced heavy rainfall, frequent typhoons, and wildfires. In response to this abnormal situation, UN Secretary-General António Guterres warned that the Earth has entered an era of boiling. With the growing awareness of environmental conservation, companies are increasingly taking on the responsibility of contributing to the SDGs and achieving carbon neutrality. Additionally, due to rising electricity costs and decreasing system installation expenses, the profitability of self-consumption solar power generation systems is improving, leading to an increase in companies adopting these systems. Our company offers "self-consumption solar power generation" systems. Please feel free to consult us when needed. [Effects] ■ Contributes to environmental conservation by reducing CO2 emissions ■ Reduces peak values by up to 30 minutes ■ Reduces air conditioning costs through heat insulation and thermal insulation effects *For more details, please download the PDF or feel free to contact us.

[Countermeasures for Rising Electricity Costs] Solved with Self-Consumption Solar Power Generation!

[Countermeasures for Rising Electricity Costs] Solved with Self-Consumption Solar Power Generation!

We will introduce self-consumption solar power generation, including the highly economical "self-investment model" and the "PPA model," which allows for the introduction of equipment without cost burden.

◆Self-Investment Model This model allows customers to purchase their own solar power generation system. Since the electricity generated can be used for free, the cost-effectiveness is maximized. - The reduction in running costs is maximized as the generated electricity can be used for free. - It allows for the utilization of the value of reduced environmental impact. - It is eligible for various preferential measures such as special depreciation and exemptions from property taxes. ◆PPA Model This is a method of installation that provides a self-consumption solar power generation system at no cost. By lending the facility's roof to the power plant owner for free, there are no costs associated with maintenance, removal, or equipment, allowing for the use of clean electricity. - The only cost incurred is for the electricity used, with no basic fee. - There are no installation or maintenance costs. - You can use 100% clean electricity generated from the roof. - Monitoring information can be visualized and used for facility PR. - If you feel the benefits are significant, purchasing the equipment midway is also possible. Implementing a self-consumption solar power generation system requires various specialized considerations, such as securing generation capacity and matching it with consumption levels. We apologize, but there may be facilities where installation is not recommended. Please contact us first regarding the feasibility of installation.
